Title: Ultrafast mid-IR sources and their impact to attoscienceAbstract: Electron recollision in an intense laser field is at the centre of attoscience research and gives rise to a variety of phenomena, ranging from the photo effect to coherent X-ray emission. We have, over the years, developed intense sources of

Title: High power multi-terawatt Field SynthesizerAbstract: A complete picture of electrodynamics in solids, with the subatomic resolution in space and time, is possible by combining x-ray diffraction and attosecond spectroscopy. This technique requires angstrom-wavelength

Title: Attosecond Optical Synthesis and ElectronicsAbstract: With the fastest optical and soft x-ray fields as a part of its repertoire, attosecond physics has opened up new avenues for exploring ultrafast electronic processes in atoms, molecules, surfaces or nanostructures.
